Abstract

Zoom Meeting is an enterprise online video conferencing solution with real-time messaging and content sharing. However, it's lack of privacy protection since centralized Zoom servers are capable of monitoring user's messages. Thereby, to solve the privacy problem, in May 2020, Zoom acquired Keybase so that Keybase's team can help it to build end-to-end encryption meeting while remaining Zoom's current scalability and high-performance. Nonetheless, according to the latest released Zoom's whitepaper, even with the new design of E2E (end to end) encryption meeting, the security threats can't be erased completely since the new design is not fully decentralized. In this paper, we introduce a fully decentralized design of E2E encryption meeting via blockchain technology. With this new design, Zoom's E2E meeting privacy can be further improved.
